The crackdown comes as FA chairman Greg Clarke said: “We need to consult with the professional game and say, ‘Come on guys. We need to work together on this one, because none of us want bad guys on the take in our game’.

“People who turn up to discuss strange deals, with strange people they have never met, are looking for trouble — and that’s what we’ve got to eliminate.

“Because, if it’s open and upfront, they can come in by the front door.”

With Wembley bigwigs still reeling, the FA’s legal department have been asked to draft a new Code of Conduct which would apply to any incoming England boss.

But Clarke added: “We have to be very careful where we draw the line because previous England managers have had deals to wear suits, watches.

“We need to figure out what we want and then figure out how to specifically exclude areas of conflict in a way that doesn’t oppress the individual.

“If a big sporting organisation wants to pay the England manager five grand to speak and he’s got the evening off, should we stop him?”
